I've noticed that pioneer scan results is much more better than philips scans. i have heard that pioneer is not best choice to scan discs btw.
ok, now i tried scan TDK media. This is multi-session disc. first session has burned in oct 2006 and second session today. Increase of PI errors over the disc is quite smooth, does this mean that the media is little bit crap? by the way, first session size is 2,25 GB. Any suggestions more?
